How Do Soundproof Curtains Work?

When people who are not familiar with the concept of soundproofing think of a soundproof room, they picture a room with a 100% isolation. Well, a room with almost 100% sound isolation and sound-absorbency actually exists, and it’s called the “quietest place on earth”. The longest anyone managed to spend in there was only 45 minutes. As sensory creatures, humans rely heavily on their senses, we kind of depend on the noises of the things around us to make sense of it, without it, the mind can create its own narrative, hallucinations in short.



It’s not unusual for humans and other animals to get adverse health effects from noise. There’s a reason sound pollution is a serious issue that is affecting the whole world. The WHO organization estimates that there are more than 120 million people worldwide with disabling hearing difficulties. Being exposed to constant sounds at a high volume can have a really high toll on the human body; it can cause tinnitus, hypertension, stress, insomnia, and many other negative effects. Studies and research show that the nervous system has a hard time maintaining deeper stages of sleep when the levels of noise are too high. You shouldn’t ignore your noisy environment as it can cause you a lot of trouble in the long run.


Soundproofing doesn’t have to be complete isolation of sound; it can also reduce it to a level that you’re comfortable with. A convenient approach to soundproofing a room or house is using noise cancelling curtains which can reduce the sounds and echoes of traffic, children in the street, dogs, and many other unpleasant sounds. This can be a matter of utmost importance as some people work from home and their living hood depends on their concentration on their work. Random noises can be very disruptive and ruin your quality of life. 


This is why we’ll be introducing a brief on how soundproof curtains work and how they can improve your home.

What to expect

You may have a dream of creating a soundproof house or room for musical or artistic purposes in general. The honest answer is that soundproof curtains won’t solely help you achieve that result, but that doesn’t mean that they won’t be a big step toward blocking a big percentage of noise volume and reducing echo. The echoes that come from within your home can become as distracting and loud as the noise coming from outside. A soundproof curtain coupled with soundproof windows or blinds can drastically change the acoustics of your room to a huge degree.

What makes it effective

A soundproof curtain doesn’t look that much different from traditional curtains, the only difference is that materials and layers used. A lot of dense and heavy materials go into the making of each layer of a soundproof curtain; the layers are a lot to provide the maximum amount of absorption. The fabrics used may differ from a manufacturer, to another, yet most of them use velvet, satin, and polyester. These materials are all very dense yet they come with a variety of textures and colors so they’d match any room or design, no less stylish than traditional curtains. You’ll notice that curtain that is good at isolating sounds, lights, and heat share the same thick materials. The thickness of the curtain material makes it more adjusted to reduce the low frequencies of sound such as bass. The porous nature of the materials helps in creating air traps that transform sound energy to heat energy, without pores the curtains would only reflect sound and have reduced efficiency.

Size and weight

Soundproof curtains are usually bigger than normal curtains as they are used to cover up the whole window and a little bit more so the folds can create seals on the sides for maximum insulation. Generally, the bigger the size of the curtain the better it is for isolation. The size of the curtain plays a role in its weight; dense materials like velvet and satin will weigh more than the normal fabric of the same size. The recommended weight for a curtain to effectively block sounds is around 1kg. You’ll want to make sure that you have a tough curtain rail or pole that is secured in place and has no chance of getting derailed off your wall as the drop-height of poles can be very dangerous. It’s preferable that your curtains are long enough to touch the ceiling and drape to the floor for maximum efficiency.

How to choose materials

We’ve mentioned that there are a few common materials that are used by soundproof curtain manufacturers. The reason these materials are chosen is that their thickness and density allow pockets of air to be trapped inside. A velvet soundproof curtain is weaved in a special method called pile weave structure. It’s made of tiny loops of velvet woven in a single direction, ensuring that the air keeps getting trapped between these loops for better absorption and blocking. The smooth and silky feel of velvet in addition to its soundproofing properties makes it one of the most sought-after materials. Another material famous for being used in soundproofing is Kilo Serge. You’ll see Kilo Serge in theatres and recording studios the most; composed of dense multiple layers of wool, which traps air and makes it easy to absorb sounds. It usually comes in solid dark colors, so in homes, it’s usually used as a curtain lining for other curtains as well. 



Soundproofing done on a professional level for specific acoustics costs a lot of money, but such soundproofing isn’t done to just block some noise from the outside, it’s done for specific lines of work. Padded walls, soundproof windows, and doors all cost multiples of what a soundproof curtain would cost. This is why the first logical solution to a noisy surrounding environment in your home is to install soundproof curtains instead of resorting to the expensive options. You’d be amazed at what they can do to your home, and their benefits aren’t exclusive to noisy environments, they can also improve the acoustics of your home and provide a more tranquil atmosphere.
